How to start

  1. Grab a transponder (build one yourself or get one from an official reseller (currently working on this..)). If you build one yourself here’s how to upload the software.
  2. Plug it in a free 5V source. Make sure you can draw enough current. Short pulses are over 100mA. Maybe an extra 47-100µF Elko on 5V rails is recommended if you notice some trouble. To set up your transponder ID follow this guide.
  3. To set up the receiver follow this guide.

Now you’re ready to go :)

ToDo :
- Wireless Usage
- What you need

What’s next

I’m working on a big update, but it’s currently a secret :P Just kidding. I have to check if what I’m planning is actually possible. If it is I will post some info here soon ;)

Main discussion about OpenLap occurs in the following Facebook group :
https://www.facebook.com/groups/1047398441948165/
Most of the discussions are in German, but I will try to make an english version of my posts in the future.

There’s also an official website, but because of limited time the info there is out of date…
www.openlap.de

Thanks for your interest in OpenLap

Always feel free to contact me, I will try to answer asap. Any “professional” help is welcome!
